Cisco QDD-400G-FR4-S Compatible 400G QSFP-DD FR4 PAM4 8 LWDM Optical Transceiver Module ( CWDM/DWDM SMF LC 2km DDM with FEC)
Cisco QDD-400G-FR4-S Compatible QDD FR4 is an advanced 400 Gigabit Ethernet (IEEE 802.3bs) transceiver that uses Long Wavelength Division Multiplexing (LWDM8) to transmit data over SMF (single-mode fiber) at speeds up to 400 Gbps. It supports eight channels of 50G 400GAUI-8 PAM4 (Pulse-Amplitude Modulation) over distances of up to 2 km using four wavelengths - 1271 nm, 1291 nm, 1311 nm, and 1331 nm. Additionally, the QDD FR4 supports Forward Error Correction (FEC) to help ensure reliable data transmission.
NADDOD 400G optical transceiver has great advantages in increasing data throughput and maximizing data center bandwidth and port density. 400G QSFP-DD has been tested and recognized by the global market as we are the first brand to complete the commercial order delivery of 400G data center optical modules.
NADDOD has a full range of professional testing equipments for testing various parameters of products to ensure high performance and quality of optical transmission stability.
